This is the chassis cab, flat 34" rails, arrived on the lot with the goofy cheap trailer lights bolted straight to the rails. The only tags inside my door frame are one with the VIN and one saying it was manufactured in Flint; my understanding of any further tags is that they are stuck on by the upfitter. Since this has never had a bed installed I don't have one with tire pressure, GVWR, etc.
The receipt has a model code starting with CK31.
I could be wrong, but I think they don't even offer dual tanks for a standard bed 3500 DRW? That's not a topic for this thread though.
